Problems solved by technology

[0003] 1. Each community needs to set up a SIP server, which is complicated to maintain, inflexible in network construction and use, and increases costs at the same time. It is not suitable for small communication networks such as building intercom in the community
[0004] 2. The SIP server set up in the community is limited by procurement and maintenance costs, and cannot meet the requirements of telecom-level use, which poses a threat to long-term reliable use. Once the SIP server fails, the building video intercom system of the entire community will be paralyzed state

example

[0037] Such as figure 1 As shown in the schematic diagram of network structure of the present invention, the difference between the present invention and the prior art is that the present invention omits the SIP server and adopts a self-contained SIP service processing module, a central processing unit, a network interface, a power supply and an input / output device The video intercom terminal makes the structure of the terminal equipment simple, easy to distribute and arrange, and the manufacturing cost is low, and is suitable for small-scale communication networks such as residential building video intercom systems.

[0038] figure 1 The role of the residential area network in the network is to connect each video intercom terminal. When the intercom terminal in the present invention uses the RJ45 interface as the external data interface, it can use any dedicated IP network or public network compatible with the IEEE802.3 standard.

Abstract

The invention relates to an SIP-based building visual intercom method and system and belongs to the technical field of visual intercom systems. According to the SIP-based building visual intercom method and system, an SIP service processing module is additionally arranged in each visual intercom terminal so that SIP account management, IP orientation and call state management of the visual intercom terminals can be achieved. The SIP-based building visual intercom system comprises one or more visual intercom terminals. Each visual intercom terminal comprises a central processor, a network interface, a power supply and an input / output device, wherein the network interface and the input / output device are connected with the central processor; the central processor comprises a visual intercom main control software module. According to the SIP-based building visual intercom system, an SIP server in the prior art is omitted so that the visual intercom terminals can be flexibly and independently arranged; the SIP-based building visual intercom system is low in cost, simple in overall structure, small in size, stable in operation and good in use effect, and the reliability of the system is improved.

Description

technical field [0001] The invention relates to a method and system for a SIP-based building visual intercom system without a SIP server, and belongs to the technical field of visual intercom systems. Background technique [0002] In the network communication system established according to the standard SIP protocol, the SIP server is the central device to realize the SIP session. The SIP server includes four main components: SIP user agent, SIP registration server, SIP proxy server and SIP redirection server. These systems pass The transmission includes the SDP protocol (used to define the content and characteristics of the message) of the message to complete the SIP session. With the networking of building video intercom products, terminals such as building video intercom system indoor units, outdoor units and management center units realize interconnection and visual intercom functions based on the SIP protocol. The application characteristics of this type of system are: ...
